SigilHook

BaseRegistered

A fee-collecting hook for Sigil protocol pools that takes a 1% cut from every swap output, routing 80% to the verified pool creator and 20% to the protocol treasury via a SigilFeeVault. Liquidity is permanently locked: only the factory can add initial liquidity, and all LP removal is blocked.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Can block LP withdrawals

It runs before liquidity is removed, so it can delay or refuse LP exits.

Gates who can add liquidity

It checks every deposit before it goes in.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
